2. In a dynamo-electric machine, acore consisting of laminae arranged in groups, toothed sheet metal disks at each end of each group, said disks having a greater stitl-- ness than the laminae and being successively shorter in the teeth, a support separate from v teeth of one of said disks being shorter than the teeth of the disk adjacent thereto,

i. In a dynan'ioelectric machine, a rotary core comprising toothed laminae, toothed sheetmetal disks of greater stiii'ness than the laminae and located at each end of the core, the teethof said disks being successively shorter and bracing the teeth of the. laminae, and end-heads having circumterentially spaced ribs bearing against the outer disks.

5.'In a dynamo-electric machine, a core comprising a plurality of groups of toothed laminae, and a plurality of spring metal dlsks at each end of each group of laminae and bracing the teeth thereof, said disks be-' ing of greater thickness than the laminae and having successively shorter teeth.

(3/111 a dynamo-electric machine, a core comprising a group of toothed lamina, a

plurality of toothed disks of different thickness from the laminae located at each end of, such group, said disks being successively shorter in the teeth.

7. In a dynamo-electric machine, a core consisting of toothed laminae arranged in groups, spacing members between said groups, and'a plurality of toothed sheet metal disks at each end of each group, the

teeth of the disks more remote from the lamime being shorter than the teeth of the disks less remote therefrom, the disks be-' ing thicker than the laminae.

8.. In a dynamo-electric machine, a core comprising a group of toothed laminae, several laminae at the end of the group being thicker than the rest and having successively shorter teeth.

In testimony whereof I affix my signature, in*the presence of two Witnesses.
